While this may be efi'ected in varieferring to the construction illustrated, ous ways, in the particular construction illus- --the supporting arm 1 is provided with a trated, the end of the block is recessed at 2% E00 to receive the end of a right and left hand threaded screw 25, a thrust collar 26 bein secured in a recess between the right and le hand threaded portions of the screw. The outer end of this screw is threaded into the hub 27 of a hand wheel 28. The outer end of this hub is recessed to receive a thrust collar 29 secured as by screws 30 to the hand wheel 3, the hand wheel 3 being secured to the sleeve 2, as by screws 31. It will be seen that on manipulation of the hand wheel 29 the block may be given a very fine adjustment relatively to the sleeve, so as to'accurately position the coned head 5 in the bore 16 of the member 6. With the construction described, therefore, the web rolls may be quickly loaded into position, and the supporting cones readily and easily adjusted.

While the invention has been shown and described in its preferred form, it will be understood that various changes can be made in the specific construction and arrangement of the parts and that the invention is not to be restricted to the exact construction shown and described.

What is claimed is 1 1. In a chuck mechanism, the combination of framing, a sleeve rotatably mounted in the framing, a concentric block, means connecting the sleeve and block so that they may have a relative axial movement but are held against relative rotation, a single cam groove in the sleeve, depressions at each end of the'groove, a spring pressed member cooperatin with the groove and arranged to enter the epressions for locking in either direction, means for rotating the sleeve to eflect a quick axial adjusting movement, and rigid means for effecting a fine adjustment of the block independently of the sleeve.

2. In a chuck mechanism, the combination of framing, a sleeve rotatably mounted in the framing, a concentric block, means COHIIQCt. ing the sleeve and block so that they may have a relative axial movement but are held against relativerotation, a single cam groove in the sleeve, depressions at each end of the groove, a spring pressed pin cooperating with the groove and arranged to enter the depres-' sions to lock the parts against rotation in either direction, a hand-wheel concentric with the sleeve for rotating it, and a concentric hand-wheel for effecting an axial movement of the block independently of the sleeve.

In testimony whereof I have hereunto set my hand.
